CYLINDER-LOCK.

SPECIFICATION'formng part of Letters Patent No. 655,145, dated July 31, 1900. Application tiled May 7, 1900. Serial No. 15,718. (No munich) To a/ZZ whom t may concern,.- l

Be it known that I, WILLIAM T. ADAMS, a citizen of the United States of America, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Cylinder-Locks, of which the following is a speciication.

My invention relates particularly to'that class of locks in which the key-cylinder and the handle-'socket are arranged opposite each other in the sides of the lock frame or case; and it consists in the improved construction and mounting of the handle-socket and in the improved clamping mechanism for interchangeably securing said key-cylinder and handle-socket in opposite positions as required for either right or left hand doors.

The invention is fully described in connection with the accompanying drawings, and the novel features are particularly pointed out in the claims.V

Figure l is an elevation showingthe outer side of the lock or latch case with the keycylinder secured in position therein. Fig. 2 is a similar view showing the inner side of the lock-case with the handle-socket and plate secured thereto. Fig. 3 is a sectional view taken mainly on the line mpx of Fig. l, the handle-socket plate being out on the line y y of Fig. 2. ,Figs. 4 and 5 are respectively a rear face and side edge view of the handlesocket plate, and Figs. 6 and 7 are separate views of the handle-socket.

A represents the usual lock case or frame, and A the removable side plate of the same. The interionmechanism, which is not shown, may be the same as is commonly employed in this class of lock and has no special bearing on my present improvements.

B represents the usual key cylinder, mounted in the cylindrical case B and provided at its inner end with the roll-back lever or arm b2 to operate the bolt. The case B is adapted, as usual, to be adj ustably and interchangeably secured in either of the similar opposite openings o? or a.' ,in the sides of the lockcase to provide for right orleft hand use of the lock. y

E represents a handle-socket having an angular opening or recess e to receive the knob or handle spindle and a roll-back arm or lever e' adapted to independently operate the bolt. In my improved construction the handle-socket E is rotatably mounted in a plate C, with the roll-back e' secured toits inwardly-projecting end, and its outer portion is formed with a collar or fiange e2 and an angular or flattened 'body e3, upon which is arranged tobear a spring D, as shown, in such a manner as to always tend to return the handle-socket and the roll-back e' to their normal positions.

The roll-back levers e of the handle-socket apd b2 of the key-cylinder, it will be understood, are arranged to act independently on the lock-bolt in in terchangeably-opposite positions. The handle-socket plate C may be `formed of sheet metal and is of somewhat? larger size than the case-openings a. a? and adapted to have a'marginal or overlapping bearing against the inner face of either side of the lock-case, while the outwardly-projecting body e2' e3 of the handle-socket and the spring D for same extend into the case side ,opening 0, or a2 without, however, projecting beyond the outer face of the case side, so as to in any Way aiect the mortising of the lock into the edge of a door.

In order to conveniently secure the handlesocket plate and also the key-cylinder case in reversibly-opposite positions, I provide 'said plate preferably with two outer lugs or projections o c', pressed therein so as to form oppositely-inclined edgewise recesses c2 c2, open at the rear ofthe plate. These lugs or projections are adapted, as shown, to enter corresponding peripheral recesses or eXtensions a3 as of either opening a' a2, thus ixedly locating the plate in proper position in the opening. It is further necessary, however, to clamp the plate against the inner face of the ease side, and this I accomplish, preferably, by means of a clamping device F, adapt ed also to simultaneously secure the key-cylinder case B in the opposite side opening, said device being capable of movement in opposite directions by means of a suitably-mounted engaging screw Gr, having its notched end geX- tended through the face-plate a of the lockcase and being provided, as shown, withA two fingers f and f', adapted to engage the plate O and case B, respectively, the latter having a longitudinal groove b', as usual, into which IOO case having similar openings through oppo# case having similar `openings through oppesaid finger f extends', While the other iinger f bears against the inclined rear -Wall of edge: wise recess o2 in the plate, thus pressing the latteroutward against the case side and riggY idly clamping the sanne. The screw F. (shown inengagement with the opposite recess c? of the plate) coperateswith the device F in irmly clamping the plate in position.

`Whatl claim is- 5H 1 1. The combination with a lock or latchV site sides, and akey-cylinder case adapted: to be secu red in either of said openings, of ahah'- dle-socket plate of larger size than said openf ings having a handle-socket rotatably mounted therein and a spring secured tothe outer face thereof andv arrangedto bear `upon the outwardlyfprojecting angular body of said handle-socket, and means for interchangeably Securing said plate against the inner face of either side of the case, with saidspring and the projecting portion` of the handlesocket extending into the opening substantially as set forth. i

2. The combination with a lock or latch site sides, and a key-cylinder case adapted to be secured in either of said openings, of a handle-socket plate of larger size" than said opening having a handle-socket rotatably mounted therein and adapted to bear against the inner face of either side of thev case, and means for simultaneously securing or releasing both the key-cylinder case and handle'- socket plate in interchangeably opposite positions in the case,'substantially`as set forth. 3. The combination with a lock or latch case having simiiarfopenings through opposite'sides, and a key-cylinder case adapted handle-socket plate having a lu g'or projection on the outer face adapted to engage a peripheral recess or Way formed in each of said openings, a single clamping ,device suitably mounted in the lock-case and adapted to engage bothv the key-cylinder case and the handie-socket plate in their interchangeable positions so as to simultaneously clamp or revleasetheV same, and an exteriorly-extended screw for operating said clamping device, *substantially as'setforth.

The combination with a lock or latch case having `similar openings through opposite side's`,`and a key-cylinder case adapted to be secured in either of said openings, of `an interchangeable handlefsocket'plate of v larger size than said openingslocatedbetween the case sides and carrying-a rotatable handie-socket, and clamping means adapted to press the overlapping portionv of said interiorly-located plate outward against the inner face of either side of the case, substantially as set forth.

5. The combination with a lock orrlatch case having similar openings through opposite sides, and a keyfcylinder case adapted to be secured in either of said openings, of a handle-socket plate of vlarger size than said openings having edgewise recesses c2 and suitably-mounted clamping devices adapted to enter said Vrecesses and wedge said plate against the inner face of the case side, substantially as set forth.
